interv_i(3PI) Sun Interval Performance Library interv_i(3PI)NAMEinterv_i - Intersection of an interval vector with another.
DESCRIPTION
Y = X INTERSECTION_WITH Y
The routine INTERV_I finds intersection of two interval vectors X and
Y and stores the result in Y. The routine returns immediately if N is
equal to zero.
SYNOPSIS
SUBROUTINE INTERV_I( X, Y )
INTERVAL, INTENT(IN) :: X(:)
INTERVAL, INTENT(INOUT) :: Y(:)
where
X and Y have shape (N).
ARGUMENTS
X (input)
Array of DIMENSION N.
Unchanged on exit.
Y (input/output)
Array of DIMENSION N.
On exit, contains intersection of X and Y.
ERRORS
blas_error_alloc
X or Y is unallocated array
blas_error_shape
shape(X) /= shape(Y)
